Did you see the regular 3d or the HFR?
I saw it in HFR, and let me tell you, it sucks in the first row. But my friend who sat a few rows back said it looked amazing.
Also, if the movie is too dark, its fake 3D. Before you go see a 3d movie, you should always look up if it was shot in 3d or if it was added after it was finished.
